Fix some paging related bugs exposed by the spawn stress test. - Process::exec() needs to restore the original paging scope when called on a non-current process. - Add missing InterruptDisabler guards around g_processes access. - Only flush the TLB when modifying the active page tables.

Lots of hacking: - Turn Keyboard into a CharacterDevice (85,1) at /dev/keyboard. - Implement MM::unmapRegionsForTask() and MM::unmapRegion() - Save SS correctly on interrupt. - Add a simple Spawn syscall for launching another process. - Move a bunch of IO syscall debug output behind DEBUG_IO. - Have ASSERT do a "cli" immediately when failing. This makes the output look proper every time. - Implement a bunch of syscalls in LibC. - Add a simple shell ("sh"). All it can do now is read a line of text from /dev/keyboard and then try launching the specified executable by calling spawn(). There are definitely bugs in here, but we're moving on forward.

Add fcntl() F_DUPFD which is slightly different from dup2().

Rework WindowServer to use select() in its main event loop. The system can finally idle without burning CPU. :^) There are some issues with scheduling making the mouse cursor sloppy and unresponsive that need to be dealt with.

mknod mnt/dev/keyboard c 85 1
Start refactoring the windowing system to use an event loop. Userspace programs can now open /dev/gui_events and read a stream of GUI_Event structs one at a time. I was stuck on a stupid problem where we'd reenter Scheduler::yield() due to having one of the has_data_available_for_reading() implementations using locks.
2019-01-14 16:21:51 +03:00
mknod mnt/dev/psaux c 10 1
Add a PTY multiplexer (/dev/ptmx) device. When you open /dev/ptmx, you get a file descriptor pointing to one of the available MasterPTY's. If none are available, you get an EBUSY. This makes it possible to open multiple (up to 4) Terminals. :^) To support this, I also added a CharacterDevice::open() that gets control when VFS is opening a CharacterDevice. This is useful when we want to return a custom FileDescriptor like we do here.
2019-01-16 15:36:10 +03:00
mknod mnt/dev/ptmx c 5 2
Add a /dev/pts filesystem and make PTY allocation dynamic. You can now open as many PTY pairs as you like. Well, it's actually capped at 8 for now, but it's just a constant and trivial to change. Unregistering a PTY pair is untested because I didn't want to start mucking with that in Terminal right now.

Finally hook up the mkdir code to a syscall. Added a /bin/mkdir that makes directories. How very neat :^) There are various limitations because of missing functionality.

cp -v ../Userland/mkdir mnt/bin/mkdir
Implement utime() along with a naive /bin/touch. This synchronous approach to inodes is silly, obviously. I need to rework it so that the in-memory CoreInode object is the canonical inode, and then we just need a sync() that flushes pending changes to disk.
2018-12-19 23:14:55 +03:00
cp -v ../Userland/touch mnt/bin/touch
Add sync() syscall and a /bin/sync. It walks all the live Inode objects and flushes pending metadata changes wherever needed. This could be optimized by keeping a separate list of dirty Inodes, but let's not get ahead of ourselves.
2018-12-20 02:39:29 +03:00
cp -v ../Userland/sync mnt/bin/sync
Add a simple /bin/more.
2018-12-21 04:42:30 +03:00
cp -v ../Userland/more mnt/bin/more
Add unlink() syscall and /bin/rm. This patch adds most of the plumbing for working file deletion in Ext2FS. Directory entries are removed and inode link counts updated. We don't yet update the inode or block bitmaps, I will do that separately.
2019-01-22 09:03:44 +03:00
cp -v ../Userland/rm mnt/bin/rm
Add support for removing directories. It's really only supported in Ext2FS since SynthFS doesn't really want you mucking around with its files. This is pretty neat though :^) I ran into some trouble with HashMap while working on this but opted to work around it and leave that for a separate investigation.

Start working on a simple graphical font editor. Editing fonts by editing text files is really slow and boring. A simple font editor seems like a good way to take LibGUI for a spin.
2019-02-02 10:05:14 +03:00
cp -v ../FontEditor/FontEditor mnt/bin/FontEditor
Start working on a simple Launcher app. Let GButton have an optional icon (GraphicsBitmap) that gets rendered in the middle of the button if present. Also add GraphicsBitmap::load_from_file() which allows mmap'ed RGBA32 files. I wrote a little program to take "raw" files from GIMP and swizzle them into the correct byte order.

Expose the kernel log buffer through /proc/dmesg. Also add a /bin/dmesg program for convenience.
2019-01-29 00:40:55 +03:00
cp -v ../Userland/dmesg mnt/bin/dmesg
Implement basic chmod() syscall and /bin/chmod helper. Only raw octal modes are supported right now. This patch also changes mode_t from 32-bit to 16-bit to match the on-disk type used by Ext2FS. I also ran into EPERM being errno=0 which was confusing, so I inserted an ESUCCESS in its place.
2019-01-29 06:55:08 +03:00
cp -v ../Userland/chmod mnt/bin/chmod
Add a /bin/top program for process table monitoring. It automagically computes %CPU usage based on the number of times a process has been scheduled between samples. The colonel task is used as idle timer. This is pretty cool. :^)

cp -v ../Userland/top mnt/bin/top
Enough compatibility work to make figlet build and run! I ran out of steam writing library routines and imported two BSD-licensed libc routines: sscanf() and getopt(). I will most likely rewrite them sooner or later. For now I just wanted to see figlet running.

Add TIOCGWINSZ ioctl so userland can determine terminal geometry. (Don't) use this to implement short-form output in ls. I'm too tired to make a nice column formatting algorithm. I just wanted something concise when I type "ls".
